A simplified method to pass the bar through the mediastinum in the Nuss technique.

In the minimally invasive repair of pectus excavatum, as reported by Nuss, the introducer is inserted into the thoracic cavity, making its way through the mediastinum, and emerges through a left intercostal space. Then, 2 umbilical tapes are tied to the introducer tip as a guide to pass into this tunnel the curved bar with the concave side up. When fat tissue is present in the anterior mediastinum or bars with notched ends are used, passage of the umbilical tape could be challenging and eventually lead to bleeding. In this report, we describe a different and simple technique to allow this passage, from left to right, in a very safe and effective way.
